I have a point feature and I want to perform a spatial join with the nearest point of another point feature (maybe even within a certain buffer distance). I know QGIS has a nice spatial join tool
"Join Attributes by Location" and I figured out what the geometric predicates do from Documentation "Join Attributes by Location" QGIS 2.18.
However, there isn't an option nearest, although the QGIS API Documentation for the
QgsGeometry class suggests that there is a class nearestPoint().
Does anyone know how to perform this kind of analysis in QGIS?
